All parts in the lower roller system 5 are installed on the basis of the working surface of the main frame 1; the whole structure of the lower roller system 5 is similar to that of the upper roller system 4, the action principle is the same, and the lower roller system 5 has no gap eliminating device and has no swinging function. The mounting positioning block 51 is used for positioning with the lower roller system 5 when the upper roller system 4 is mounted, so that the mounting accuracy is ensured, and the mounting positioning block 51 is removed after the mounting is completed.
In order to ensure the safety of the plate leveling process and avoid the damage of equipment caused by overload, the invention specifically designs a hydraulic safety protection device, wherein the hydraulic cushion 19 is an oil cylinder with the stroke of about 20mm and only supplies oil to the plug cavity. The hydraulic cushion 19 cooperates with the balance cylinder 24 to realize the equipment safety protection in the plate leveling process, and the protection process is as follows: 1. by arranging a pressure sensor, the pressure in the piston cavity of the hydraulic cushion 19 is measured, and the measurement result is fed back to a numerical control system; 2. calculating the pressure in a plug cavity of the hydraulic cushion 19 under the maximum bearing capacity according to the maximum bearing capacity of the leveler design, setting the pressure in a numerical control system as the maximum safe use pressure, and comparing the maximum safe use pressure with the measured pressure of the pressure sensor in real time; 3. the numerical control system sets a protection program, and when the detected feedback pressure in the plug cavity of the hydraulic cushion 19 is larger than the maximum safe use pressure set by the system, the system automatically executes the protection program: the hydraulic cushion 19 is depressurized in a plug cavity, the balance cylinder 24 is lifted to drive the floating beam 6 and the upper roller system 4 to lift to the height, and the plate leveling process is terminated; 4. when a user uses the leveling machine in a violation way to level a plate exceeding the maximum processing capacity of the equipment, the pressure in the plug cavity of the hydraulic cushion 19 is detected to exceed the set value of the system, the protection program is automatically executed, the upper roller system 4 is lifted, the leveling force in the equipment is reduced, and the equipment damage caused by overload use is avoided.
As shown in fig. 9, the adjustment of the angle a is performed, that is, the adjustment of the roll gap angle is realized. As shown in fig. 10, the vertical distance h between the upper and lower work rolls is adjusted to adjust the roll gap shape. As shown in fig. 11 and 12, the roll convexity adjustment is achieved by changing the deflection of the work roll, fig. 11 is a concave-convex type, and fig. 12 is a convex-concave type.
